BELT GUIDE AND THROWIN'G DEVICE.

Specification of Letters Patent.

Patented Nov. 10, 1914.

Application filed August 16, 1913. Serial No. 785,176.

following is a specification, reference being had therein to the accompanylng drawing.

This inventlon relates to an engine attachment and the principal ob ect of the invention is to provide an engine attachment for a traction engine by means 01 which the belt may be disconnected from the fly wheel.

Another object of the invention is to so construct the attachment that it may be connected with any engine regardless of the angle to which the sides of the engine are pitched.

Another object of the invention is to so construct the device that it may be adjusted to fit the width of any belt used. WVith these and other objects in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed. 1

This invention is illustrated in the aecompanying drawings, wherein:

Figure 1 is aside elevation of the traction engine provided with the improved belt shifting mechanism. Fig. 2 is a fragmentary top plan view of the engine provided with an improved belt shifting means. Fig. 3 is a perspective view of the belt shifting mechanism. Fig. 4.- is a bottom plan view of the belt shifting mechanism shown in Fig. 3. Fig. 5 is a perspective view of the lever for operating the shifting mechanism. Fig; 6 is a sectional view through the operat ing mechanism, shown in Fig. 5 andtaken along the line 66. Fig. 7 is a view showing the arm upon which the belt engaging means is slidably mounted, thesleeve which ismounted upon the arm being shown in sec tion. Fig. 8 is a section along the line 88 in Fig. 41. Fig. 9 is aperspeetive view of the link which connects the sliding sleeve with the belt crank. y

i This invention is intended tobe used in connection with the boiler of the traction engine 10 and is intended to provide means whereby thebelt 11 may be guided while traveling around the fly. wheel 12 and readily disconnected from the fly wheel when desired.

This invention is provided with a base plate 13 which is preferably curved, shown in Fig. 3 and secured to the side of the boiler by rivets 1 1 extending through the corners of the plate. .An arm 15 extends from one end portion of the plate 13 and is provided with a clutch head 16. A red 17 extends from thearm 15 and is provided with an enlarged head 18 at its inner end, which head 18 forms a clutch head which is adjustably connected to the clutch head 16 with the pivot pin 19. By this means the rod 17 may be held at any desired angle so that the rod may be at the proper angle no mat ter at what angle the sides of the boiler extend.

Asleeve 20 is slidably mounted upon the rod 17 and is provided with a supporting arm 21 which extends from its inner end and forms a supporti'orthe axle 22 of the roller 23. A. ring 21 which carries an arm 25 is mounted upon the outer end of the sleeve and is adjustably held in place by means of the set-screw 26 so that the ring may be moved upon the sleeve according to the width R of the belt which passes around the fly wheel. A secondary roller 27 is rotatably mounted upon the axle 28. This axle 28 is provided with the enlarged head 29 which prevents the removal. of the roller 27 and is connected 1 to the arm 25 by means of the pin 30 passing through the arm 25 and lower end of the axle 28. From an inspection of Figs. 3 and. 8 it will be readily seen that this ring 24: can be very readily adjusted upon the sleeve 20 and that therefore, the distance between the rollers 23- and 27 can be regulated so that the rollers will engage the edges of the belt passing between them, thus guiding the belt and preventing the same from moving to one side and slippingfrom the fly wheel... i

A bell-crank lever 31 is pivotally mounted upon the reduced end 32 of the supporting arm 33 and limits the pivotal movement in one direction by the shoulder 34 at the inner end of the reduced end 32. This bell-crank lever has one arm 35 extended as shown in Fig. 4 and has its end portion pivotally mounted between the forks 36 at the inner end of the link 37. This link 37 has its outer end portion provided with opening 38 through which the lower end of the axle 22 passes. This link is held in connection with the axle by means of the key 22, and it will be readily seen that when the bell crank lever moves, it will move the sleeve from one end of the rod 17 to the other. By shifting this sleeve from the inner end of the rod *17 and the outer end, the belt will be drawn away ,fromthe boiler and will thus be disconnected from the fly wheel 12.

A bracket 39 is secured to the rear end of the boiler by means of the rivets 40 and is provided with an upper flange 41 which is supportedby the webs 42 and carries an up standing arm 43 which arm 43 is provided with a clutch face shown in Fig. 6. A rack 44 is pivotally connected with the arm 43 by means of a pin 45 which pin passes through the sleeve 46 at the base of the rack 44. This sleeve 46 is provided with a clutch face 'which engages the teeth of the clutch face and adjustably connects the rack with the arm .43 so that the rack will be held at the desired angle irrespective of the pitch of the boiler face. A latch lever 47 is pivotally connected with the rack by means of the pivot pin 48 and is provided with a latch 49 which engages the teeth of the rack so that the lever may be held in an adjusted position. .A rod 50 connects the latch lever with the bell-crank lever and from an inspection of the drawings and particularly Fig. 2, it will be readily seen that when the latch lever is moved, the bell-crank lever willbe rocked uponthis pivot pin 51, thus causing the sleeve 20 to be moved upon the rod 17.

A. device has. therefore been provided which may be readily connected with any boiler irrespective of the slope of the outer face of the boiler, and which may be used with a belt of any width.

WVhat is claimed is:

1; An. attachment of the character described comprising a supporting plate, a rod extending from said plate and adjustably connected therewith, a bellcrank lever pivotally connected with said plate, a sleeve slidablymounted upon said rod, an arm carried by said sleeve, a roller, ania-xle for said roller passing through said arm, a link connectingthe lower end of said axle with the end of saidarm, a bracket carriedby said sleeve, a rollerrotatably connected with said bracket, and means for rocking said bellcranlrlever.

2. An attachment of the character described comprising a supporting plate, a rod extending from said supporting plate, a belt shifting means mounted upon said rod, a bell-crank lever pivotally connected with said plate and connected with said belt shifting means, a second supporting plate, an arm extending above said second supporting plate and provided with a clutch face, a rack, a sleeve carried by said rack and provided with a clutch face, a pin pivotally connecting said sleeve with said arm whereby the clutch faces of said sleeve and arm will interlockto hold said rack in an adjusted position, a latch pivotally connected with said rack, and a means connecting said latch lever with said bellcrank lever whereby the movement of said latch lever will rock said bell-crank lever. I
